AGM Statement

Vernalis plc ("Vernalis" or the "Company") provides an update ahead of its Annual General Meeting ("AGM") being held today at 10.30 am at the offices of Covington & Burling, 265 Strand, London WC2R 1BH.

Highlights

Tuzistra® XR prescriptions continue to grow steadily, up 85% on prior year (1 July to 1 Dec)

With c.70% of 2017/18 cough cold season remaining, Tuzistra® XR needs to see an acceleration in prescription growth to achieve the annual guidance of 105,000-115,000 prescriptions

Next update: end of Q1 2018 – in conjunction with interim results release

CCP-07 and CCP-08 NDAs remain on track for approval during 2018/19 financial year

Research business continues to perform well

Ian Garland, CEO of Vernalis commented: "We are encouraged by the steady growth in Tuzistra® XR prescriptions, despite the general negativity, in the US, surrounding the use of narcotic-based drugs. Whilst we need to see acceleration in prescription growth to achieve our total prescription market guidance of a threefold increase in prescription volume, we are early in the cough cold season and the US commercial team is executing a disciplined plan to accelerate growth over the coming months."

Tuzistra® XR and the cough cold franchise

Tuzistra® XR scripts grow 85%

Tuzistra® XR prescriptions for the 22 weeks from 1 July 2017 to 1 December 2017, the latest weekly data available, are up approximately 85% on the equivalent 22 week period of the prior year. Although we have seen steady growth, this growth will need to accelerate in the four months to March 2018, when typically almost half of the annual cough cold prescriptions are written (2016/17 approximately 49% of annual total), if we are to achieve our target growth of 200% over the prior year. We will provide a further update at the end of Q1 2018 when we announce our interim results for the six months to 31 December 2017.

The growth in Tuzistra® XR prescriptions seen in the first 22 weeks of 2017/18 is against a background of a continuing decline in the narcotic portion of the prescription cough cold market. Year-to-date, the combined prescribing of codeine and hydrocodone-based cough cold products is down 13% compared to the same period in the prior year, which itself was down 14% compared to 2015/16. Over the past two years, the combined prescribing of codeine and hydrocodone cough products has fallen by 25%. This decline in prescribing reflects continued public focus on the level of usage of opiate based products that are prescribed to treat pain. Although the use of opiates in a short term acute setting to treat cough cold is not the principal area of concern, we are still seeing a significant impact on prescribing.

In addition to this decline in the level of narcotic prescribing, restrictions on the size of narcotic prescriptions have also been introduced by some US States, health insurance plans and physicians. This has resulted in a decline in the average size of a Tuzistra® XR prescription from approximately 160 mL in the prior year to approximately 145-150 mL in the current year-to-date. This decline in prescription size will have an impact on the net sales value of each Tuzistra® XR prescription.

CCP-06, our non-narcotic cough cold product continues to progress and will allow us to fully exploit potential of franchise

The prescription cough cold market comprises both narcotic and non-narcotic based products and the dynamics highlighted above only impact the narcotic portion. This is important because of the mix of cough cold products in our portfolio. We have one non-narcotic product in development (CCP-06) and our two most advanced pipeline products (CCP-07 and CCP-08), like Tuzistra® XR, are both targeting the narcotic portion of the market but include additional active ingredients that can extend their market reach.

CCP-07/08 NDAs still on track for approval during 2018/19 financial year

In April 2017 and August 2017, we announced that we had received Complete Response Letters (CRLs) for CCP-07 and CCP-08 respectively and would provide further information related to the issues raised by the FDA and the implications on the timing of their re-submissions and potential approvals. We are now able to provide updated information regarding these CRLs.

In early 2017, FDA undertook an inspection at Tris and identified certain non-product related issues needed to be addressed. Given the issues identified, FDA determined that it was unable to approve CCP-07 on its 20 April 2017 PDUFA date and instead issued a CRL, indicating that these issues needed to be addressed before re-submission of the NDA could occur. On 4 August 2017, although Tris had made good progress in addressing the issues, FDA was unable to approve the CCP-08 NDA and issued a CRL for that product. The CRL for CCP-08 indicated that the FDA wanted evidence that the issues identified in its inspection at Tris did not impact the CCP-08 NDA. This evidence includes manufacturing new batches of CCP-08 and could require repeating the pivotal bio-equivalence studies on which approval was sought.

Tris is working diligently to address the issues raised by FDA and specifically as they relate to the NDAs for CCP-07 and CCP-08. This includes the support of external expert consultants and regular discussions with FDA. We continue to believe that both NDAs are approvable and could potentially be resubmitted and subsequently approved during our 2018/19 financial year.

Moxatag®

We continue to progress qualification of a new supplier of Moxatag® and expect to be back in supply during 2018. We continue to focus on increasing pharmacy stocking since its re-launch in September and will provide a more detailed update when we announce our interim results at the end of Q1 2018.

Research Business continues to perform well

The research business continues to perform to plan having secured a €1m milestone from the third collaboration with Servier (as recently announced) as well as two new collaborations, including one recently announced with Daiichi Sankyo.

Cash position is in line with expectations

The Company's unaudited cash position (including cash and cash equivalents and held to maturity assets), remains strong and at 11 December 2017, was £48.9 million. The cash position has been negatively impacted by the weakening of the US dollar since 30 June 2017, with a significant proportion of our cash denominated in that currency.

No additional material information or updates on trading will be given at Vernalis' AGM today. The presentation to be given will be available on the company website after the AGM.
